On Monday, Hairston made the switch.
"I reevaluated what I wanted in my college experience and Louisville had all of what I was looking for, so I had to jump all over that opportunity," he told Cardinal Authority. "I thought that was the best decision for me to make."
Monday marked the start of a contact period that allows coaches to call prospects and Louisville made Hairston, a Perfect Game Top 500 prospect, a priority. Cardinal assistant Chris Lemonis called him at the stroke of midnight and the early hours conversation was rewarding, as Hairston committed to the Cardinals.
"I told the coaches on Monday," he explained. "That was the first day that coaches could call and I got a call at exactly 12 O'clock from Coach Lemonis. The head coach, Coach Mac, called me around 10 O'clock and I talked to him for about 30 minutes on the phone and I told him that I would be playing for him in a couple years."
Hairston is currently in Georgia, participating in the 17U World Wood Bat National Championship, where he could face fellow 2014 commit and friend Drew Ellis of Jeffersonville (Ind) High School.
"Me and Drew have been playing against each other during the summer for about four years now," said Hairston, who plays for the Kentucky Baseball Club. "He plays for the Indiana Bulls. We text every now and then just to catch up with each other. We are both very competitive players, so I'm looking forward to working on the same team as him."
Hairston's attention will now be focused on improving and helping guide Tates Creek back to the state tournament. For the First Team All-State performer, the recruiting process is over.
"I've shut it down to all the other schools," he said. "I'm not going to back out of this commitment. We made sure that this would the right choice. I had to tell a couple of schools that I'm going to Louisville and that I appreciated the opportunities that they gave me, but I'm happy with my decision and I don't need to look anymore."
